I was told about this book by a co-worker and I gotta tell ya, it is a good book. Before reading it I thought I was alone in feeling frustrated, and doubting my artistic abilites. It is an uplifting book and makes you think about all those doubts and turn them into positive. I purchased it from Amazon but I'm sure it is available at most book stores. I encourage you to check it out.
